https://astrogeology.usgs.gov/search/map/Moon/LRO/LOLA/Lunar_LRO_LOLA_Global_LDEM_118m_Mar2014 - Lunar DEM with formula Height = (Pixel Value * Scaling Factor) Conversion to local Radius (meters) is computed as follows: Radius = (Pixel Value * Scaling factor) + 1737400 where Scaling Factor = 0.5 (as listed in the label as Multiplier) lunar reference radius of 1737400.0 m - dug9 opinion: it looks not bad as a texture too Using Gimp, resampled 1024x512 image to 128x64, then saved as .c - wrote a .c program to re-write as .x3d GeoElevationGrid - prints to console, so redirect > your.x3d Then used that node with imageTexture using the 1024.jpg https://astrogeology.usgs.gov/search/map/Moon/Kaguya/TC/Ortho/v02/Lunar_Kaguya_TC_Ortho_Global_64ppd_v02 - japan ortho image
